[Music] we have quite a lot of questions regarding also the basis you're saying that most of the equations are based on ame so we talk about how to measure this amb and the first component i would say on the any equation so one question from angelique can i use aae from nir system to calculate the net energy uh yes i think in one of the slides i presented in the introduction uh i said that the net energy can be calculated from any good indicator uh of the de or the me uh or the digital nutrients content so so nowadays i mean the equations which are available are only those based on d e or me i mean d e or m e measured so why not pre using or predicting the d e or the m e value of an ingredient or even a diet according to let's say infrared methods and use that prediction for calculating the energy yes i truly agree on that but the point is that you should be very you should be very careful uh for instance when the net energy equation is proposed it is proposed with uh amy uh or let's say for pigs i mean the the point is much less important but for uh for poetry you the net energy equations will be based on any values but you should be careful about which amy you are talking about uh is it i mean it is very popular to use me for zero nitrogen balance so if you use a me for zero natural imbalance as a predictor you should use a net energy equation where the me for zero nitrogen balance is used as a predictor so be careful when you use equations look at the units look at the definition of the predictors and so on and use the right equations with the right numbers so you should be very careful so why not using infrared values if the infrared are predicting let's say men or ames or amy for me for layers for poetry for for breeders and for i don't know any type of animal so be careful when using net energy equation look at the units look at the predictors do they apply to any type of animals and so on there is a very interesting point so care you want to uh to have a comment yeah i think i fully agree with the point of sean that a lot of questions should be carried on on the on the values of me that you can see there and many many books and many nis values are giving the metabolisable energy corrected for zero nitrogen balance and you should care that your equation is taking these parameters into account and another comment would be that i think that both the idea of of moving to ne is to be closest to the animal requirement and to be more precise so nia the precise nutrition values that you can get having an ayah are going in the same way so for me the two strategies are going in the same way moving to any and using the best values the best nutritional values of your raw material that you can get john you want to add something yeah yeah i just want to add a comment maybe i think uh just because some questions are more focused on poetry uh i think it's time to to abandon or to move from amy n in poultry to a more reliable and more representative amy predictor clearly amy doesn't mean means nothing for poultry i think all the the riders all the layers in the world are not on the zero natural balance they are only 50 or 60 of the nitrogen intake that is retained in the body so which should move to a much more representative predictor of amy and i mean the feeding tables unfortunately are mainly based on amen but uh the touch should be corrected in the future to move to some standardized amy which is more representative of the practical conditions
